A mass of 0.3kg is suspended from a spring of stiffness 200Nm-1. If the mass is displaced by 10mm from its equalibrium position and released, for the resulting vibration calculate: The maximum velocity of the mass during the vibration.
v = Aωcos(wt+∅)
The Attempt at a Solution
Now ω = 25.82cos.
so v = A 25.82cos (25.82t+∅)
So now i have to find A (amplitude) and t (displacement)
Is displacement the same as the amplitude?
Not sure on how to find the amplitude? Any guidance would be appreciated.
